Use createdesktop to create a desktop with nothing left, and then run explorer in the new desktop environment, so there is a desktop with the same functions as windows, now you have two desktops. The following is how to use switchdesktop to switch between different desktops.

Programs opened on different desktops are invisible on the taskbar of other desktops, including the system tray, but they are still visible in the task manager, which makes it very convenient to do a lot of things, many... it can also be quickly transferred to a normal state, so that people who scold you, such as the boss, can have nothing to say, because they can't see anything :)

Or you can customize a personalized desktop for your users. You can change the code above to get the desired effect.
